Portfolio Moves and the Exit

A second door is bought with the first door's numbers, not its story. The equity you built, the ratio the rent supports, the reserves you refuse to touch, and the full cost of selling are the whole decision, and none of them changes because you like the property.

This chapter runs those four numbers in the order investors actually face it: the cash-out ladder, the fast lane through it, the keep-or-sell test, a stress test of the whole portfolio, the discipline of not buying, and the exit. Then the book ends the way it began, with the cast in one table.

The ladder

Equity in door one funds door two, and the ratio, not the equity, sets how much you can pull. A cash-out refinance on a rental commonly carries a seasoning requirement measured in months, an LTV ceiling around 75%, and the coverage test again on the new, larger loan. The cash-out pillar owns those mechanics in full; this is what they do to the duplex.

Two years after the close from Chapter 5, Close and the First 90 Days, an illustrative scenario at stated inputs and no appreciation assumed, the duplex's loan balance is $194,943. The rent supports a loan of $234,954 at the 1.25 cushion. The LTV ceiling at the purchase price allows $198,750.

Duplex, end of year two	Loan the limit allows	Cash out after paying off the balance
Ratio limit, rent supports 1.25	$234,954	$40,011
LTV limit, 75% of value	$198,750	$3,807

The smaller number governs, and at these inputs it's the LTV limit: without appreciation, the value hasn't moved, so the only new borrowing room is the principal you paid down. That is the ladder in a flat market. It climbs at the speed of amortization unless rent or value rises.

Either way, the number that funds door two is the smaller of the two, minus closing costs, and it was decided by the rent and the payment before you ever called a lender.

BRRRR, the ladder run faster

Buy, renovate, rent, refinance, repeat is the ladder with the renovation doing the appreciating. The BRRRR guide owns the method; this chapter owns one portfolio-level correction to how it's usually sold.

The metric that matters is capital recovered as a percentage of capital invested, not the count of doors. A door that returns 80% of your cash at the refinance and cash-flows on the new loan is a ladder rung. A door that returns 100% and loses money every month afterward isn't an infinite return. It's a negative-cash-flow property you own for free, which is still a negative-cash-flow property.

The standing doctrine: recovered capital counts only when the hold cash-flows on the refinanced loan, measured the way Chapter 3, Underwriting the Expense Stack, measures everything, with the real stack and the real payment.

Keep or sell

Equity sitting in a door earns a return whether you notice or not, and the keep-or-sell decision is that return against what the same equity would earn somewhere else. Three numbers settle it, and appreciation isn't one of them, because a keep decision that depends on appreciation is a bet and gets labeled one.

On the duplex in year three, an illustrative scenario at stated inputs: the equity trapped in the door is $70,057, the price minus the balance. It earns $3,228 in cash and $2,128 in principal reduction this year, a return on that equity of 7.6%.

Selling costs money first. At 7% all-in, a stated illustrative figure, the sale costs $18,550, leaving $51,507 before recapture, which Chapter 7, The Tax Layer, hands to your CPA. Redeployed into a second duplex at identical terms, that equity would earn $3,228 a year in cash flow.

At these inputs the door you own earns more than the door you'd buy with its equity, once the cost of selling is counted, and the answer doesn't depend on the property appreciating. Keep, and let the next door come from the ladder rather than from a sale.

Run the same test on any door with the rental property calculator, and run it every year, because equity grows and so does the return the market would pay for it elsewhere.

Stress test the portfolio, not the property

A portfolio fails in ways a single property can't, because the shocks arrive together. Three are worth modeling before the next purchase, and the book's three doors, the duplex's two and the Washington single-family, carry the test.

The Washington property enters the portfolio here, bought at $270,000, an illustrative price set below the break-even that Chapter 8, Regulatory Risk You Underwrite For, computed, at its proven $2,350 rent and house terms. It covers at 1.30 with $15 a month, which is what buying at the fallback price buys you. The portfolio's baseline is $284 a month across three doors.

Shock	Portfolio cash flow that month
Baseline, all doors paying	$284
All three doors vacant in the same month	-$4,042
Insurance repriced 30% higher on both properties	$194
Duplex refinanced at 8.5% instead of 7.5%	$160

The first shock is why reserves exist at the portfolio level, not the property level: a single bad month across every door is a number, and it's on the table. The second is why Chapter 3, Underwriting the Expense Stack's insurance rule never retires. The third is why the ladder's next rung is a rate bet unless you've computed it, and why a credit cycle with non-QM delinquencies at 5.76%, elevated relative to history,¹ is a reason to model the refinance before you count on it.

Your own break point is the shock that turns the portfolio's month negative for longer than your reserves last. Find it before the market does.

When to stop buying

One more door is the mission when the last door is performing, and only then. That's the whole brand in one sentence, and it's a reject rule at portfolio scale.

Three limits decide it:

• a reserve floor: this portfolio's is $21,576, six months of every door's full obligation, and no purchase is allowed to breach it;
• a concentration limit: one metro, one insurer, or one tenant type carrying too much of the whole, which the stress table above already priced;
• the difference between scaling and accumulating: scaling adds doors the expense stack can carry; accumulating adds doors only the plan on paper can carry, and only the first survives a bad year. Chapter 6, Operating in a Flat-Rent Market, already warned where self-management breaks; the third door is usually it.

One concentration risk is written into a state where we operate. In Tennessee, a group of single-family rentals owned and managed as one operation was classified as commercial property, taxed at the 40% ratio instead of 25%, because the assessor and the courts looked at the portfolio, not the parcels.² Structure at scale is a tax input, and Chapter 4, The Financing Decision, already told you vesting is a decision.

Exit mechanics

A sale is priced by three things: what it costs to sell, what the depreciation costs on the way out, and what the calendar allows. Sale costs first, on the duplex in year three: at 7% all-in, $18,550 against a balance of $192,816, leaving $53,634 before tax, an illustrative scenario at stated inputs.

Recapture is the second cost, and it belongs to Chapter 7, The Tax Layer, and your CPA: the depreciation you took is repriced at sale. The 1031 exchange defers it by rolling the gain into a replacement property, and its mechanics live in the exchange guide and its companion on financing the replacement property.

The calendar is the third, and it's the one that surprises people: an exchange gives you 45 days from the sale to identify the replacement and 180 days to close on it.³ Those clocks start at closing, not at listing, which means the replacement property gets underwritten through this whole book, buy box to expense stack to fallback test, on a deadline. Investors who exchange well have the next door in the buy box from Chapter 2, Buy Box Before You Shop, before the current one is under contract.

The whole cast, three years on

Every door this book followed, in one table, an illustrative scenario at stated inputs. The duplex, three years in; the Washington single-family, bought at the fallback price; and the Miami single-family, which never closed and never should have.

Door	Status	Coverage ratio	Monthly cash flow	Run it
The duplex, $265,000	Stabilized, year three	1.46	$269	rerun
Washington single-family, $270,000	Bought at the fallback price, under the cap	1.30	$15	rerun
Miami single-family, $476,598 asking	Rejected in chapter 2	0.87	needed $325,608 to clear 1.25	rerun

Three doors, three verdicts, and every number in the table reconciles to the engines that computed it in the chapter where it first appeared.

The duplex was negotiated to its floor, closed, stabilized, tested against turnover, and now tested against a refinance and a sale. The Washington property was refused at asking and bought at the price the fallback test dictated. Miami was rejected on sight and rescued on paper twice, and the box won anyway.

That's the book: a set of rules that hold from the first listing to the last closing, with the arithmetic done in public. The toolkit carries those rules as four documents you fill in yourself: the buy box that decides whether the next door qualifies, the underwriting sheet that runs it, the checklist you clear before the offer, and the scorecard that tells you whether the last door is performing, which is the one test this chapter says has to pass before you buy again. The cash-out ladder, the keep-or-sell test and the exit math stay in the calculators linked above; the toolkit holds the rules, the calculators do the arithmetic.

The two questions every chapter answers. On the ratio: at portfolio scale it's the thing that decides what you can extract, what you can refinance, and whether the next door adds to the portfolio or drags on it. On cash flow: it's the reserve that survives the month all three doors go quiet, and the reason the last door has to perform before the next one gets bought.
